$\displaystyle \frac{\partial^2 w}{\partial t\partial x}-
\left(\frac 1w\frac{\partial w}{\partial t}+b\right)\frac{\partial w}{\partial x}-\frac{c}{w}\frac{\partial w}{\partial t}-c b= 0$.
%where $b$ and $c$ are constants.
The general solution:\hfill\break
$\displaystyle w(t,x) = \left\{-c\int\,\exp[-e^{bt}G(x)]\,dx+F(t)\right\}\exp[e^{bt}G(x)]$,\hfill\break
where $F(t)$ and $G(x)$ are arbitrary functions.
Remarks:This PDE is particular case of PDEs family EQ 19
